IMPROVEMENT lN COVERS FOR HOLDING TABLETS.

Specification forming part of'Letters Patent No. 204.118, dated May 21, 1878 application filed March 14, 1878.

To all whom it may concern:

Be it known that I, HENRY WILLsoN, of Chicago, in the county of Cook and State of Illinois,-have' invented certain new and useful Improvements in Tablet-Gases, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof, and in which- Figure 1 is a perspective View of an open case embodying my invention, and having tablets applied thereto; Fig. 2, a top view or representation of the inside of one leaf of the case when the tablet is rem0ved;'Fig. 3, a like representation, showing the movable or adjustable slide or clamp more in detail; and Fig. 4, a section through one of theleaves of the case, and through an adjustable clasp applied thereto.

Like letters of reference indicate like parts.

My object is to make a case which may be applied with facility to paper tablets and easily removed from the pasteboard base when the sheets which form the tablets are detached. The class of tablets herein referred to are those made by arranging a number of sheets one upon the other, and connecting the edges by means of strips attached thereto, the Whole being applied to a pasteboard base. I

In the drawing, Are presents the tablet; a a, the strips by means of which the edges of the sheets forming the tablet are connected together; and a, the base of the tablet.

B is the tablet-case, consisting of stifi parts or covers b b, united to each .other by means of the flexible back b. O G are clasps, clamps, or hooks, applied rigidly to the inner end of the part b, to which the tablet A is to be applied. The exposed or bent ends of the clasps O G are turned from the back b, and stand far enough above the inner face of the cover to receive or clasp one end of the part a. O O are movable clasps, applied to the outer end of the part or cover b, to which the" clasps O (l are applied. The bent ends of the clasps 0"0 extend toward the clasps O O, and are raised sufficiently above the inner face of the cover to receive or clasp the end of the part a, as is clearly shown in Figs. 3 and 4. The clasps O C are adjustable, and may be pushed back and forth, so as to release and clamp the part a alternately when so moved, and according to the direction of movement.

To render the clasps O 0 adjustable for this purpose, they may be slotted, as shown at d, and held to the part a by means of one or more headed pins or rivets, c, passing through the said slots and entering the part b to which the clasps are applied. The clasps O G, however, may be rendered adjustable, for the purpose set forth, in any well-known or convenient way;

The clasps may also be arranged on the sides of the case, or so as to engage the sides of the tablet, and in such case they may be pivoted to the case.

In order to apply the tablet A to the case B, the clasps O '0 should be drawn outward, and one end of the board or part a .pushed underneath the projecting ends of the clasps O O. The clasps (l 0 should then be pushed inwardly, so as to clasp the outer end of the I parta, as represented inFigs. 1 and 4. By this means the tablet will be firmly held to the case and protected. When the leaves of the tablet are all removed, a new tablet may be applied with facility in the manner described, the base of the tablet being also removed.

D is a blottingtablet, applied to the inner face of that part of the case which is intended to be folded over the tablet A.

The tablet D may consist of several sheets stuck together at the ends or edges by means of any suitable adhesive material, and the tablet so formedmay be applied to the case by means of a little mucilage put upon the lower leaf. Only a small amount of mucilage should be applied to the edges of the sheets of the tablet D, so that the said sheets may be easily removed, one by one, without tearing the remaining sheets.

If deemed best, the sheets of the tablet D may be united to each other by means of strips like a a.

It will be perceived from the foregoing that I combine a blotting-tablet with the same case to which the writing-tablet is applied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Atablet-ca consisting of the leaves I) b, structed and arranged to clasp the upper face flexibly conn ted to each other, one of the said of the base-piece a, substantially as and 1 for leaves being provided with one or more blotthe purposes specified. ting-sheets, and the other with elasps for clasping the edges of a tablet of writing-sheets, HENRY WILLSON' substantially as and for the purposes specified. Witnesses:

2. The tablet-case provided with the fixed F. F. WARNER,

clasps G O and the movable elasps O O, con- AUG. FRENCH.
